以一个多媒体地理信息系统的模型为例,从感性上进一步理解上述概念和原则。 地理信息系统(IS: geography information system)是一个对地理信息进行存储、管理、 分析、加工的复杂计算机应用系统。GIS处理的数据信息涉及大量的图文表示和空间要素分 析。传统的方法已无法适应,利用面向对象设计方法可以对GIS要素加以合理的抽象, 且这种抽象在概念上是自然的、简洁的、易于理解的

在求解线性方程组(System of Linear Equations)的算法中,有两类最基本的算法,一类 是直接法,即以消去为基础的解法。如果不考虑误差的影响,从理论上讲,它可以在固定 步数内求得方程组的准确解。另一类是迭代解法,它是一个逐步求得近似解的过程,这种 方法便于编制解题程序,但存在着迭代是否收敛及收敛速度快慢的问题

In this lecture, we will derive expressions for the angular momentum and kinetic energy of a 3D rigid body. We shall see that this introduces the concept of the Inertia Tensor. Angular Momentum We start form the expression of the angular momentum of a system of particles about the center of mass
